The submental lymph nodes collect lymph from the central area of the lower lip, the skin of the mental region, the tip of the tongue, and the incisor teeth. Next, they drain into the submandibular lymph nodes and the deep cervical group, which eventually drains into the jugular lymph trunk.
Why do submental lymph nodes swell?
Most of the time, they're caused by swollen lymph nodes. This swelling is typically triggered by an infection. Cancer, cysts, abscesses, benign tumors, and other medical issues can also cause chin lumps. However, these causes are much rarer by comparison.
Where is the submental lymph node?
The submental glands (or suprahyoid) are situated between the anterior bellies of the digastric muscle and the hyoid bone. Their afferents drain the central portions of the lower lip and floor of the mouth and the apex of the tongue.
